Abstract: A double fertiliser hopper is mounted on a frame attachable to a tractor. Each hopper has an outlet (11) in its floor through which the fertiliser falls onto a rotary disc with radial vanes which spread the fertiliser over the soil surface. Each outlet is opened or closed by two pivoted slides (12,13), mounted one above the other. One slider can be fully opened or fully closedby a hydraulic cylinder (22) controlled by the tractor driver. The second slider is set at a fixed degree of opening before beginning to spread the fertiliser. The first slider is then fully closed and, when the tractor reaches the field to be spread, is fully opened.

Abstract: The compressor (21) delivers refrigerant to the condenser unit (22), which is blown by a fan (27) of the outdoor unit, along a line. A second line for refrigerant by-passes the condenser.  The ratio of flow-rate in the first line to flow-rate in the second line is controlled by a condensing pressure  control valve (25) of the variable pressure-setting type, which is disposed at the junction of the two lines. The control signal for the valve, and for an expansion valve (23) disposed in the line from the condensing pressure control valve to the evaporator (24), is supplied by the controller (35). This effects an arithmetical operation on two signals, . one from a compression ratio sensor (34) which detects the ratio of delivery and suction pressures at the compressor, and the other from a superheat sensor (33). This detects degree of superheat at suction port of compressor (21). Room temperature is sensed (32)  and signalled to the controller.

Abstract: An electrical load (RL) is fed from a smoothing capacitor (C3) across the  output of a DC-DC converter circuit.
